Communications device media delivery

ABSTRACT

A communications device determines the appropriate method for providing a message depending upon the content of the message without prompting or querying a user of the device. When the user selects a name as the recipient of the created message, the mobile device determines delivery options. If the message contains text only and if the user enters/selects a mobile device phone number, the message is sent via SMS. If the message contains multimedia and if the user enters or selects a mobile device phone number, the message is sent via MMS. If the message is text only or multimedia, and if the user enters or selects an email address, the message is sent via email. In various implementations, the message is delivery via determined delivery options including a lowest cost delivery option, a subscriber preferred delivery option, or a delivery options as indicated by an intended recipient&#39;s presence information.

BACKGROUND

Current implementations and standards for the support of multimedia onmobile devices is complex. For example, a typical mobile device promptsa user with a query asking if the user wants to send a message via SMS,MMS, or email. This requires the user to have knowledge of andunderstand the various types of multimedia delivery methods (e.g., SMS,MMS, email), the differences between the various types of multimediadelivery methods, and how to use the various types of multimediadelivery methods.

SUMMARY

A communications device determines the appropriate method for providinga message depending upon the content of the message. The communicationsdevice determines the content type, automatically, without providing aprompt to, or querying a user of the communications device, unless thecontent type is undeterminable. For example, if the message containstext only and if the user enters a phone number or selects a phonenumber from an address book, the message is sent via SMS. If the messagecontains multimedia (e.g., video, a picture) and if the user enters aphone number or selects a phone number from the address book, themessage is sent via MMS. If the message is text only or multimedia (withor without text), and if the user enters an email address (e.g.,name@domain.xxx) or selects an email address from the address book, themessage is sent via email.

In an example embodiment, if there are multiple delivery options, thelowest cost option is selected. For example, a text message could besent via SMS to the recipient cell phone number of 555-580-1234 or couldbe sent as an email message to 5555801234@txt.att.net. Both addresseswill deliver the text message to the same mobile device of the intendedrecipient. However, it is possible that one method could be moreexpensive. In an example embodiment, if there are multiple deliveryoptions and the subscriber has indicated a preference for messagedelivery (either for this subscriber or for all messages), the messageis delivered via the subscriber preferred delivery method, thus possiblyoverriding the lowest cost option.

Thus, in an example scenario, when a subscriber selects an intendedrecipient of a message, the mobile device finds the intended recipientin the internal address book of the device (or at any appropriatelocation). Based upon the media type of the message (e.g., text only,text and multimedia attachment, etc.), based upon cost factors (e.g.,unlimited SMS messaging plan, international roaming charges), based uponnetwork presence information for the intended recipient, and based uponsubscriber preferences in the address book, the mobile deviceautomatically selects the appropriate delivery method.

In another example embodiment, if the intended recipient's contactinformation in the subscriber's address book contains multiple emailaddresses (e.g., email address of PC, email address of mobile device),and the subscriber has not indicated which address is preferred and ifthere is a presence service available, the message is delivered inaccordance with the presence information as follows. If presence isindicated only on the mobile device, the message is delivered to themobile device email address. If presence is indicated only on the PC,the message is delivered to the PC email address. If presence isindicated on both the mobile device and the PC, the message can bedelivered to either the mobile device email address or the PC emailaddress, or the message can be sent to a default email address.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

FIG. 1 is a flow diagram depicting an example process for providingmedia via a mobile communications device. The content type of a messageto be sent via a mobile communications device is determined at step 12.If the content type is text only (step 14) and a phone number isavailable or has been entered or selected, the message is sent via theShort Message Service (SMS) at step 16. If the content type ismultimedia (step 18), which can include text, and a phone number isavailable or has been entered or selected, the message is sent via theMultimedia Message Service (MMS) at step 20. Multimedia, as depictedherein includes any content type other than text only. Thus multimediacan include an image, audio, video, or any combination thereof, or textin any combination with an image, audio, video. Text can include plaintext and rich text. If, at step 18, it is determined that the messagecontent does not include multimedia, the mobile communications deviceprovides a request, at step 22, for the content type to be utilized. Therequest, in an example embodiment, comprises a query on a display of themobile communications device asking for a delivery method content type.In various embodiments, the user can select from a menu of content typesor enter a content type.

FIG. 2 is another flow diagram depicting an example process forproviding media via a mobile communications device. At step 24, it isdetermined if an email address of the intended recipient is available orhas been entered or selected via the mobile communications device. If anemail address is available or has been entered or selected, the messageis provide via email at step 26. If an email address is not available orhas not been entered or selected, the address, or addresses, of theintended recipient is determined at step 28. The address can include anyappropriate address, such as a phone number, URL or the like. Theaddress can be obtained by the user entering an address or selecting anaddress. The address can be obtained from an address book by the user,automatically by the mobile communications device, or a combinationthereof.

At step 30 it is determined if multiple delivery options for providingthe message to the intended recipient are available. For example, a textmessage could be sent via SMS to the recipient cell phone number (e.g.,555-580-1234) or could be sent as an SMS message via a gateway to anemail message to an email address (e.g., 5555801234@txt.att.net). Bothaddresses will deliver the text message as an SMS message to the samemobile device of the intended recipient. If multiple delivery optionsare not available (step 30), the message is provided via the availabledelivery method at step 32.

If multiple delivery options are available (step 30), it is determined,at step 34, if the subscriber associated with the mobile communicationsdevice has a preferred delivery method. For example, the subscribercould enter a default preferred method to send the message to a phonenumber. If, at step 34, it is determined that the subscriber has apreference, the message is provided, at step 36, via the preferreddelivery method.

If, at step 34, it is determined that the subscriber does not have apreference, it is determined, at step 38, if a presence service isavailable. As known, a presence service provides an indication of theability and/or willingness of the intended recipient to communicate. Ifit is determined, at step 38, that no presence service is available, themessage is sent via that lowest cost delivery method at step 40. Thelowest cost delivery method can be determined in any appropriate manner.For example, the user/subscriber can enter the lowest cost deliverymethod or the mobile communications device can determine the lowest costdelivery method in accordance with the subscribers profile, currentrates, etc.

If it is determined, at step 38, that presence service is available, itis determined, at step 42, if multiple delivery options are available.For example, the intended recipient may have a mobile communicationsdevice and a PC via which the intended recipient can receive messages.Thus, the presence service could indicate presence (the intendedrecipient is willing/able to communicate) for the intended recipient'smobile device, PC, or both (e.g., multiple delivery options). If it isdetermined, at step 42, that multiple delivery options are notavailable, the message is delivered in accordance with the presenceindicated delivery method. That is, for example, if presence indicatesthe intended recipient's mobile device, the message is sent to theintended recipient's mobile device, or if presence indicates theintended recipient's PC, the message is sent to the intended recipient'sPC.

If it is determined, at step 42, that multiple delivery options areavailable (e.g., presence indicated on both the intended recipient'smobile device and the intended recipient's PC), the message is deliveredvia that lowest cost delivery method at step 40.

FIG. 4 depicts an overall block diagram of an exemplary packet-basedmobile cellular network environment, such as a GPRS network, in whichmedia can be provided via a communications device as described herein.In the exemplary packet-based mobile cellular network environment shownin FIG. 4, there are a plurality of Base Station Subsystems (“BSS”) 400(only one is shown), each of which comprises a Base Station Controller(“BSC”) 402 serving a plurality of Base Transceiver Stations (“BTS”)such as BTSs 404, 406, and 408. BTSs 404, 406, 408, etc. are the accesspoints where users of packet-based mobile devices become connected tothe wireless network. In exemplary fashion, the packet trafficoriginating from user devices is transported via an over-the-airinterface to a BTS 408, and from the BTS 408 to the BSC 402. Basestation subsystems, such as BSS 400, are a part of internal frame relaynetwork 410 that can include Service GPRS Support Nodes (“SGSN”) such asSGSN 412 and 414. Each SGSN is connected to an internal packet network420 through which a SGSN 412, 414, etc. can route data packets to andfrom a plurality of gateway GPRS support nodes (GGSN) 422, 424, 426,etc. As illustrated, SGSN 414 and GGSNs 422, 424, and 426 are part ofinternal packet network 420. Gateway GPRS serving nodes 422, 424 and 426mainly provide an interface to external Internet Protocol (“IP”)networks such as Public Land Mobile Network (“PLMN”) 450, corporateintranets 440, or Fixed-End System (“FES”) or the public Internet 430.As illustrated, subscriber corporate network 440 may be connected toGGSN 424 via firewall 432; and PLMN 450 is connected to GGSN 424 viaboarder gateway router 434. The Remote Authentication Dial-In UserService (“RADIUS”) server 442 may be used for caller authentication whena user of a mobile cellular device calls corporate network 440.

Generally, there can be a several cell sizes in a GSM network, referredto as macro, micro, pico, femto and umbrella cells. The coverage area ofeach cell is different in different environments. Macro cells can beregarded as cells in which the base station antenna is installed in amast or a building above average roof top level. Micro cells are cellswhose antenna height is under average roof top level. Micro-cells aretypically used in urban areas. Pico cells are small cells having adiameter of a few dozen meters. Pico cells are used mainly indoors.Femto cells have the same size as pico cells, but a smaller transportcapacity. Femto cells are used indoors, in residential, or smallbusiness environments. On the other hand, umbrella cells are used tocover shadowed regions of smaller cells and fill in gaps in coveragebetween those cells.

FIG. 5 illustrates an architecture of a typical GPRS network in whichmedia can be provided via a communications device as described herein.The architecture depicted in FIG. 5 is segmented into four groups: users550, radio access network 560, core network 570, and interconnectnetwork 580. Users 550 comprise a plurality of end users. Note, device512 is referred to as a mobile subscriber in the description of networkshown in FIG. 5. In an example embodiment, the device depicted as mobilesubscriber 512 comprises a mobile device (e.g., mobile wirelesscommunications device 46). Radio access network 560 comprises aplurality of base station subsystems such as BSSs 562, which includeBTSs 564 and BSCs 566. Core network 570 comprises a host of variousnetwork elements. As illustrated in FIG. 5, core network 570 maycomprise Mobile Switching Center (“MSC”) 571, Service Control Point(“SCP”) 572, gateway MSC 573, SGSN 576, Home Location Register (“HLR”)574, Authentication Center (“AuC”) 575, Domain Name Server (“DNS”) 577,and GGSN 578. Interconnect network 580 also comprises a host of variousnetworks and other network elements. As illustrated in FIG. 5,interconnect network 580 comprises Public Switched Telephone Network(“PSTN”) 582, Fixed-End System (“FES”) or Internet 584, firewall 588,and Corporate Network 589.

A mobile switching center can be connected to a large number of basestation controllers. At MSC 571, for instance, depending on the type oftraffic, the traffic may be separated in that voice may be sent toPublic Switched Telephone Network (“PSTN”) 582 through Gateway MSC(“GMSC”) 573, and/or data may be sent to SGSN 576, which then sends thedata traffic to GGSN 578 for further forwarding.

When MSC 571 receives call traffic, for example, from BSC 566, it sendsa query to a database hosted by SCP 572. The SCP 572 processes therequest and issues a response to MSC 571 so that it may continue callprocessing as appropriate.

The HLR 574 is a centralized database for users to register to the GPRSnetwork. HLR 574 stores static information about the subscribers such asthe International Mobile Subscriber Identity (“IMSI”), subscribedservices, and a key for authenticating the subscriber. HLR 574 alsostores dynamic subscriber information such as the current location ofthe mobile subscriber. Associated with HLR 574 is AuC 575. AuC 575 is adatabase that contains the algorithms for authenticating subscribers andincludes the associated keys for encryption to safeguard the user inputfor authentication.

In the following, depending on context, the term “mobile subscriber”sometimes refers to the end user and sometimes to the actual portabledevice, such as a mobile device (e.g., mobile wireless communicationsdevice 46), used by an end user of the mobile cellular service. When amobile subscriber turns on his or her mobile device, the mobile devicegoes through an attach process by which the mobile device attaches to anSGSN of the GPRS network. In FIG. 5, when mobile subscriber 512initiates the attach process by turning on the network capabilities ofthe mobile device, an attach request is sent by mobile subscriber 512 toSGSN 576. The SGSN 576 queries another SGSN, to which mobile subscriber512 was attached before, for the identity of mobile subscriber 512. Uponreceiving the identity of mobile subscriber 512 from the other SGSN,SGSN 576 requests more information from mobile subscriber 512. Thisinformation is used to authenticate mobile subscriber 512 to SGSN 576 byHLR 574. Once verified, SGSN 576 sends a location update to HLR 574indicating the change of location to a new SGSN, in this case SGSN 576.HLR 574 notifies the old SGSN, to which mobile subscriber 512 wasattached before, to cancel the location process for mobile subscriber512. HLR 574 then notifies SGSN 576 that the location update has beenperformed. At this time, SGSN 576 sends an Attach Accept message tomobile subscriber 512, which in turn sends an Attach Complete message toSGSN 576.

After attaching itself with the network, mobile subscriber 512 then goesthrough the authentication process. In the authentication process, SGSN576 sends the authentication information to HLR 574, which sendsinformation back to SGSN 576 based on the user profile that was part ofthe user's initial setup. The SGSN 576 then sends a request forauthentication and ciphering to mobile subscriber 512. The mobilesubscriber 512 uses an algorithm to send the user identification (ID)and password to SGSN 576. The SGSN 576 uses the same algorithm andcompares the result. If a match occurs, SGSN 576 authenticates mobilesubscriber 512.

Next, the mobile subscriber 512 establishes a user session with thedestination network, corporate network 589, by going through a PacketData Protocol (“PDP”) activation process. Briefly, in the process,mobile subscriber 512 requests access to the Access Point Name (“APN”),for example, UPS.com, and SGSN 576 receives the activation request frommobile subscriber 512. SGSN 576 then initiates a Domain Name Service(“DNS”) query to learn which GGSN node has access to the UPS.com APN.The DNS query is sent to the DNS server within the core network 570,such as DNS 577, which is provisioned to map to one or more GGSN nodesin the core network 570. Based on the APN, the mapped GGSN 578 canaccess the requested corporate network 589. The SGSN 576 then sends toGGSN 578 a Create Packet Data Protocol (“PDP”) Context Request messagethat contains necessary information. The GGSN 578 sends a Create PDPContext Response message to SGSN 576, which then sends an Activate PDPContext Accept message to mobile subscriber 512.

Once activated, data packets of the call made by mobile subscriber 512can then go through radio access network 560, core network 570, andinterconnect network 580, in a particular fixed-end system or Internet584 and firewall 588, to reach corporate network 589.

FIG. 6 illustrates an exemplary block diagram view of a GSM/GPRS/IPmultimedia network architecture 600 within which media can be providedvia a communications device as described herein. As illustrated,architecture 600 of FIG. 6 includes a GSM core network 601, a GPRSnetwork 630 and an IP multimedia network 638. The GSM core network 601includes a Mobile Station (MS) 602, at least one Base TransceiverStation (BTS) 604 and a Base Station Controller (BSC) 606. The MS 602 isphysical equipment or Mobile Equipment (ME), such as a mobile phone or alaptop computer that is used by mobile subscribers, with a Subscriberidentity Module (SIM) or a Universal Integrated Circuit Card (UICC). TheSIM or UICC includes an International Mobile Subscriber Identity (IMSI),which is a unique identifier of a subscriber. The BTS 604 is physicalequipment, such as a radio tower, that enables a radio interface tocommunicate with the MS. Each BTS may serve more than one MS. The BSC606 manages radio resources, including the BTS. The BSC may be connectedto several BTSs. The BSC and BTS components, in combination, aregenerally referred to as a base station (BSS) or radio access network(RAN) 603.

The GSM core network 601 also includes a Mobile Switching Center (MSC)608, a Gateway Mobile Switching Center (GMSC) 610, a Home LocationRegister (HLR) 612, Visitor Location Register (VLR) 614, anAuthentication Center (AuC) 618, and an Equipment Identity Register(EIR) 616. The MSC 608 performs a switching function for the network.The MSC also performs other functions, such as registration,authentication, location updating, handovers, and call routing. The GMSC610 provides a gateway between the GSM network and other networks, suchas an Integrated Services Digital Network (ISDN) or Public SwitchedTelephone Networks (PSTNs) 620. Thus, the GMSC 610 provides interworkingfunctionality with external networks.

The HLR 612 is a database that contains administrative informationregarding each subscriber registered in a corresponding GSM network. TheHLR 612 also contains the current location of each MS. The VLR 614 is adatabase that contains selected administrative information from the HLR612. The VLR contains information necessary for call control andprovision of subscribed services for each MS currently located in ageographical area controlled by the VLR. The HLR 612 and the VLR 614,together with the MSC 608, provide the call routing and roamingcapabilities of GSM. The AuC 616 provides the parameters needed forauthentication and encryption functions. Such parameters allowverification of a subscriber's identity. The EIR 618 storessecurity-sensitive information about the mobile equipment.

A Short Message Service Center (SMSC) 609 allows one-to-one ShortMessage Service (SMS) messages to be sent to/from the MS 602. A PushProxy Gateway (PPG) 611 is used to “push” (i.e., send without asynchronous request) content to the MS 602. The PPG 611 acts as a proxybetween wired and wireless networks to facilitate pushing of data to theMS 602. A Short Message Peer to Peer (SMPP) protocol router 613 isprovided to convert SMS-based SMPP messages to cell broadcast messages.SMPP is a protocol for exchanging SMS messages between SMS peer entitiessuch as short message service centers. The SMPP protocol is often usedto allow third parties, e.g., content suppliers such as newsorganizations, to submit bulk messages.

To gain access to GSM services, such as speech, data, and short messageservice (SMS), the MS first registers with the network to indicate itscurrent location by performing a location update and IMSI attachprocedure. The MS 602 sends a location update including its currentlocation information to the MSC/VLR, via the BTS 604 and the BSC 606.The location information is then sent to the MS's HLR. The HLR isupdated with the location information received from the MSC/VLR. Thelocation update also is performed when the MS moves to a new locationarea. Typically, the location update is periodically performed to updatethe database as location updating events occur.

The GPRS network 630 is logically implemented on the GSM core networkarchitecture by introducing two packet-switching network nodes, aserving GPRS support node (SGSN) 632, a cell broadcast and a GatewayGPRS support node (GGSN) 634. The SGSN 632 is at the same hierarchicallevel as the MSC 608 in the GSM network. The SGSN controls theconnection between the GPRS network and the MS 602. The SGSN also keepstrack of individual MS's locations and security functions and accesscontrols.

A Cell Broadcast Center (CBC) 14 communicates cell broadcast messagesthat are typically delivered to multiple users in a specified area. CellBroadcast is one-to-many geographically focused service. It enablesmessages to be communicated to multiple mobile phone customers who arelocated within a given part of its network coverage area at the time themessage is broadcast.

The GGSN 634 provides a gateway between the GPRS network and a publicpacket network (PDN) or other IP networks 636. That is, the GGSNprovides interworking functionality with external networks, and sets upa logical link to the MS through the SGSN. When packet-switched dataleaves the GPRS network, it is transferred to an external TCP-IP network636, such as an X.25 network or the Internet. In order to access GPRSservices, the MS first attaches itself to the GPRS network by performingan attach procedure. The MS then activates a packet data protocol (PDP)context, thus activating a packet communication session between the MS,the SGSN, and the GGSN.

In a GSM/GPRS network, GPRS services and GSM services can be used inparallel. The MS can operate in one of three classes: class A, class B,and class C. A class A MS can attach to the network for both GPRSservices and GSM services simultaneously. A class A MS also supportssimultaneous operation of GPRS services and GSM services. For example,class A mobiles can receive GSM voice/data/SMS calls and GPRS data callsat the same time.

A class B MS can attach to the network for both GPRS services and GSMservices simultaneously. However, a class B MS does not supportsimultaneous operation of the GPRS services and GSM services. That is, aclass B MS can only use one of the two services at a given time.

A class C MS can attach for only one of the GPRS services and GSMservices at a time. Simultaneous attachment and operation of GPRSservices and GSM services is not possible with a class C MS.

A GPRS network 630 can be designed to operate in three network operationmodes (NOM1, NOM2 and NOM3). A network operation mode of a GPRS networkis indicated by a parameter in system information messages transmittedwithin a cell. The system information messages dictates a MS where tolisten for paging messages and how to signal towards the network. Thenetwork operation mode represents the capabilities of the GPRS network.In a NOM1 network, a MS can receive pages from a circuit switched domain(voice call) when engaged in a data call. The MS can suspend the datacall or take both simultaneously, depending on the ability of the MS. Ina NOM2 network, a MS may not have received pages from a circuit switcheddomain when engaged in a data call, since the MS is receiving data andis not listening to a paging channel In a NOM3 network, a MS can monitorpages for a circuit switched network while received data and vice versa.

The IP multimedia network 638 was introduced with 3GPP Release 5, andincludes an IP multimedia subsystem (IMS) 640 to provide rich multimediaservices to end users. A representative set of the network entitieswithin the IMS 640 are a call/session control function (CSCF), a mediagateway control function (MGCF) 646, a media gateway (MGW) 648, and amaster subscriber database, called a home subscriber server (HSS) 650.The HSS 650 may be common to the GSM network 601, the GPRS network 630as well as the IP multimedia network 638.

The IP multimedia system 640 is built around the call/session controlfunction, of which there are three types: an interrogating CSCF (I-CSCF)643, a proxy CSCF (P-CSCF) 642, and a serving CSCF (S-CSCF) 644. TheP-CSCF 642 is the MS's first point of contact with the IMS 640. TheP-CSCF 642 forwards session initiation protocol (SIP) messages receivedfrom the MS to an SIP server in a home network (and vice versa) of theMS. The P-CSCF 642 may also modify an outgoing request according to aset of rules defined by the network operator (for example, addressanalysis and potential modification).

The I-CSCF 643, forms an entrance to a home network and hides the innertopology of the home network from other networks and providesflexibility for selecting an S-CSCF. The I-CSCF 643 may contact asubscriber location function (SLF) 645 to determine which HSS 650 to usefor the particular subscriber, if multiple HSS's 650 are present. TheS-CSCF 644 performs the session control services for the MS 602. Thisincludes routing originating sessions to external networks and routingterminating sessions to visited networks. The S-CSCF 644 also decideswhether an application server (AS) 652 is required to receiveinformation on an incoming SIP session request to ensure appropriateservice handling. This decision is based on information received fromthe HSS 650 (or other sources, such as an application server 652). TheAS 652 also communicates to a location server 656 (e.g., a GatewayMobile Location Center (GMLC)) that provides a position (e.g.,latitude/longitude coordinates) of the MS 602.

The HSS 650 contains a subscriber profile and keeps track of which corenetwork node is currently handling the subscriber. It also supportssubscriber authentication and authorization functions (AAA). In networkswith more than one HSS 650, a subscriber location function providesinformation on the HSS 650 that contains the profile of a givensubscriber.

The MGCF 646 provides interworking functionality between SIP sessioncontrol signaling from the IMS 640 and ISUP/BICC call control signalingfrom the external GSTN networks (not shown). It also controls the mediagateway (MGW) 648 that provides user-plane interworking functionality(e.g., converting between AMR- and PCM-coded voice). The MGW 648 alsocommunicates with other IP multimedia networks 654.

Push to Talk over Cellular (PoC) capable mobile phones register with thewireless network when the phones are in a predefined area (e.g., jobsite, etc.). When the mobile phones leave the area, they register withthe network in their new location as being outside the predefined area.This registration, however, does not indicate the actual physicallocation of the mobile phones outside the pre-defined area.

While example embodiments of providing media via a communications devicehave been described in connection with various computingdevices/processor, the underlying concepts can be applied to anycomputing device, processor, or system capable of providing and/orreceiving usage information pertaining to usage of a mobile wirelesscommunications device.

In thecase of program code execution on programmable computers, the computingdevice will generally include a processor, a storage medium readable bythe processor (including volatile and non-volatile memory and/or storageelements), at least one input device, and at least one output device.The program(s) can be implemented in assembly or machine language, ifdesired. The language can be a compiled or interpreted language, andcombined with hardware implementations.

The methods and apparatuses for providing media via a communicationsdevice also can be practiced via communications embodied in the form ofprogram code that is transmitted over some transmission medium, such asover electrical wiring or cabling, through fiber optics, or via anyother form of transmission, wherein, when the program code is receivedand loaded into and executed by a machine, such as an EPROM, a gatearray, a programmable logic device (PLD), a client computer, or thelike, the machine becomes an apparatus for the utilization of on-demandspam reporting. When implemented on a general-purpose processor, theprogram code combines with the processor to provide a unique apparatusthat operates to invoke the functionality of providing media via acommunications device. Additionally, any storage techniques used inconnection with the utilization of providing media via a communicationsdevice can invariably be a combination of hardware and software.

While providing media via a communications device has been described inconnection with the various embodiments of the various figures, it is tobe understood that other similar embodiments can be used ormodifications and additions can be made to the described embodiment forperforming the same functions of providing media via a communicationsdevice without deviating therefrom. For example, one skilled in the artwill recognize that providing media via a communications device asdescribed in the present application may apply to any environment,whether wired or wireless, and may be applied to any number of suchdevices connected via a communications network and interacting acrossthe network. Therefore, providing media via a communications deviceshould not be limited to any single embodiment, but rather should beconstrued in breadth and scope in accordance with the appended claims.
